=== Get role mappings API
++++
<titleabbrev>Get role mappings</titleabbrev>
++++

Retrieves role mappings.

[[security-api-get-role-mapping-request]]
==== {api-request-title}

`GET /_security/role_mapping` +

`GET /_security/role_mapping/<name>` 

[[security-api-get-role-mapping-prereqs]]
==== {api-prereq-title}

* To use this API, you must have at least the `manage_security` cluster privilege.

[[security-api-get-role-mapping-desc]]
==== {api-description-title}

Role mappings define which roles are assigned to each user. For more information, 
see <<mapping-roles>>.

The role mapping APIs are generally the preferred way to manage role mappings
rather than using <<mapping-roles-file,role mapping files>>.
The get role mappings API cannot retrieve role mappings that are defined
in role mapping files.

[[security-api-get-role-mapping-path-params]]
==== {api-path-parms-title}

`name`::
  (Optional, string) The distinct name that identifies the role mapping. The name
  is used solely as an identifier to facilitate interaction via the API; it does
  not affect the behavior of the mapping in any way. You can specify multiple 
  mapping names as a comma-separated list. If you do not specify this
  parameter, the API returns information about all role mappings. 

[[security-api-get-role-mapping-response-body]]
==== {api-response-body-title}

A successful call retrieves an object, where the keys are the
names of the request mappings, and the values are the JSON representation of 
those mappings. For more information, see 
<<role-mapping-resources>>.

[[security-api-get-role-mapping-response-codes]]
==== {api-response-codes-title}

If there is no mapping with the requested name, the
response will have status code `404`.


[[security-api-get-role-mapping-example]]
==== {api-examples-title}

The following example retrieves information about the `mapping1` role mapping:
